Vercel shipped AI SDK 7. It's not an update. This is an SDK-wide shift from 'calling a model' to a full-fledged agent platform, aimed squarely at production maturity.
The keyword is 'resilience.' An agent that dies on restart is good for a demo and nothing more. One that's running orders for a real customer needs to survive a deploy mid-work, wait hours for human approval, and pick up exactly where it left off - without forgetting what it was doing. The SDK takes on exactly that - resumable execution, signed approvals, timeouts. They're building it for people who are already running agents in their business and can't afford a crash mid-task. Whether it holds up in the field remains to be seen.
